Drug-drug. Aminoglycosides: elevated aminoglycoside blood level (in premature infants)

Beta-adrenergic blockers: reduced antihypertensive effect

Bisphosphonates: increased risk of gastric ulcers

Cholestyramine: decreased etodolac absorption

Cyclosporine: increased risk of nephrotoxicity

Diuretics: decreased diuretic effect

Lithium: increased lithium blood level, greater risk of toxicity

Methotrexate: increased risk of methotrexate toxicity

Phenylbutazone: increased etodolac effects

Phenytoin: increased phenytoin blood level

Salicylates: decreased etodolac blood level

Drug-diagnostic tests. Bleeding time: prolonged

Blood urea nitrogen (BUN), creatinine, hepatic enzymes: increased levels

Urine bilirubin, urine ketones: falsepositive results

Drug-herbs. Arnica, chamomile, clove, dong quai, feverfew, garlic, ginkgo, ginseng: increased risk of bleeding

White willow: increased etodolac effects

Drug-behaviors. Alcohol use: increased risk of adverse effects

Sun exposure: phototoxicity

Patient monitoring

• Monitor CBC, liver function tests, BUN, creatinine level, and coagulation studies.

• Assess for GI bleeding and gastric upset. Administer antacids as needed and prescribed.

• Know that drug may cause falsepositive urine bilirubin and urine ketone test results.

Monitor patient for signs and symptoms of thrombocytopenia and increased bleeding time.

• Assess for fluid retention and weigh patient daily.

• Watch for decreased blood pressure control in hypertensive patients.

Patient teaching

• Instruct patient to take with meals if possible.

• Tell patient to swallow extendedrelease tablets whole without crushing or chewing.

Instruct patient to immediately report unusual bleeding or bruising, change in urination pattern, unusual tiredness, or yellowing of skin or eyes.

• Advise patient to avoid activities that can cause injury.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, herbs, and behaviors mentioned above.

All the NSAIDs (diclofenac, dipyrone, etodolac, and ketoprofen) produced significant analgesic effects in the hot plate test (p<0.01 and p<0.001).
She was diagnosed as DRESS syndrome caused by the CM and etodolac due to (1) the close relationship between the initiation of CM and etodolac and the onset of symptoms, (2) the elimination rate of CM and etodolac in elderly patients are reduced related to the reduction in renal function and aging,[sup][6] (3) the risk of acute nephrotoxicity of NSAIDs increases with age,[sup][7] (4) fever, (5) skin rash with facial edema, (6) typical laboratory tests included the presence of eosinophilia and atypical lymphocytes, (7) a positive finding of CMV infection which is associated with the development of DRESS, (8) multiple organ involvement including the liver, kidney, lung, and pancreas, and (9) persistent and worsening symptoms after withdrawal from the causative drug.
As appearing from the loadings in Figure 2(b), (1) basic drugs, terfenadine, toremifene, nadolol, carvedilol, and haloperidol, and (2) acidic drugs, diclofenac and etodolac, have a big weight on PC1 and PC2, respectively, in comparison to the other drugs, which indicate that they play a main role in column classification.
Traditional NSAID use (diclofenac, etodolac, and meloxicam) is also associated with decreased risk in developing aggressive skin cancers, whereas "more selective" to COX-2 inhibitors were not found to be protective [133,134].
Those taking a specific COX-2 called etodolac were 53% more likely to die from stroke compared to non-users.
The product is a novel, chrono-modulated combination of the non-selective beta-adrenergic receptor blocker, propranolol, and the COX-2-selective non-steroidal anti-inflammatory drug (NSAID), etodolac.
The applications of non-classical bioisosterism have also been reported in a number of areas of pharmacology including adrenergic and anti adrenergic drugs [28, 30-31] , several NSAID classes like aryl acetic acid derivatives [32], cetroplac, tolmetin, indomethacin, etodolac [5], antibacterial drugs [33] , antidepressant of morpholine class [34] , neuropeptide substance P antagonists (NK1 antagonists) [35], cholinergic (muscarinic type) agonists [36], GABA modulators like muscimol, thiomuscimol, isomuscimol as agonists [37-38], peptidomimetics [39], diuretics like ethacrinic acid [5] and 5-hyderoxy tryptamine (5-HT1A;1D) agonists like naratryptan and sumatryptan for acute attack of migraine [40].
Etodolac (1,8-diethyl-1,3,4,9-tetrahydropyrano[3,4b]-indole-1-aceticacid, ETD, Figure 1(b)) isapotent andwelltolerated nonsteroidal anti-inflammatory drug (NSAID), and is indicated for the treatment of acute pain and for the signs and symptoms of rheumatoid arthritis and osteoarthritis [3].
A eficacia dos diferentes AINEs, sejam COX-2 seletivos (celecoxibe), parcialmente seletivos (meloxican, nabumetone e etodolac) ou classicos (nao seletivos--diclofenaco, naproxeno, ibuprofeno, indometacina, dentre outros), foi semelhante quando a dose de cada medicamento e empregada com mesma extensao.
